Arterial macroaneurysm of the retina.

Macroaneurysms of the retinal arteries were found in both eyes of a patient suffering from systemic hypertension. The development of the aneurysms were related to high blood pressure attacks. Treatments with low energy laser coagulation reduced the aneurysms, preserving good patency of the vessels. In the right inferior temporal artery, an untreated focal narrowing deteriorated to an occlusive fibroblastic proliferation, emphasizing how damaging the course of the disease may be.
